In chemistry and physics, cohesion refers to the sticking together of alike molecules, such as water molecule being attracted to another water molecule. Cohesion also causes water molecules to form drops.
Together with adhesion It helps to explain the occurrence of surface tension and capillary action.
In botany, cohesion pertains to the fusion of plant parts, such as in syncarpy.

This type of bond determines the cohesiveness of water molecules?
hydrogen bonds
What determines the cohesiveness of water molecules?
Hydrogen bonds
Surfactant helps to prevent the alveoli from collapsing by what?
Interfering with the cohesiveness of water molecules, thereby reducing the surface tension of alveolar fluid.
What gives rise to the cohesiveness of water molecules?
Water Molecules are polar molecules. That means that one end of the molecule has a slight positive end and one end has a slight negative end. Then just like a magnet, the positive end poles the negative end connecting the two.
Describe the biological significance of the cohesiveness of water?
Well, one really big and well known reason is that it allows water to be transported through plants. The sun exaporates water and cohesion allows the water to be sucked up to the leaves from the bottom even with gravity pulling down on it because of the constantly reformed hydrogen bonds.
What are cohesiveness?
it means how things are sticking together
How important is cohesiveness to productivity?
It varies with the job or product involved. The term generally means how well people work together or in concert. To a mountain fur trapper who works alone, cohesiveness means nothing. To a football team, cohesiveness is the only thing that will keep from losing the game badly.
Which biological process is associated with the cohesiveness of water molecule?
Hydrogen bomds
Why is water extremly cohesive?
Water is polar, meaning the Hydrogen and Oxygen molecules in the water have an uneven distribution of electrons. This causes an attraction between the water molecules poles, like magnets, which draws them together. The water Hydrogen Bond also affects cohesiveness because each oxygen molecule in water has 2 lone pairs of electrons which can each form a Hydrogen bond with the hydrogen from another water molecule
What is crystallization of water?
It is basically is how many molecules are in a hydrated compound, for example CuSO4.7H2O means that for every Copper Sulphate molecules, there are 7 water molecules around it.
Why does a water drop form a sphere?
Water (H2O) is very cohesive, meaning that its molecules tend to stick to each other. Cohesion of water is especially strong due to an H2O's ability to make up to 4 hydrogen bonds with other water molecules. This principle is also responsible for the common elementary experiment in which many drops of water are dropped on a penny head, yet the water manages to stay on top. Its cohesiveness is due to
What will dissolve?
Salt can dissolve in water because the salt molecules hide between the water molecules so that means it can dissolve but it hasn't dissapeared in the water
